Hi Rob, The solution you proposed looks correct. I do not think it is possible to build it in a more efficient way, as the libraries can only be built with one transport defined at a time. Best regards, Jørgen

Re-building OpenThread Libraries - Thread SDK4.0.0 - missing libopenthread-cli-ftd.a and libopenthread-cli-mtd.a

My error. When running a fresh build as described above, the files are generated.

I made the mistake of running a "make -f examples/Makefile-nrf52840 .... with the NCP_SPI=1 flag set first (which inhibits the CLI). I failed to issue a "make -f examples/Makefile-nrf52840 clean" before making the UART or USB variants (which DO include the CLI).

So I understand the corrected script (rebuilding SDK4.0.0 for GCC or SES without modification), in linux, is as follows:

sudo apt-get update
sudo apt-get upgrade
mkdir ot
cd ot
git clone https://github.com/openthread/openthread.git
cd openthread
git checkout 8a1992e2e42fb707babe9491a6a1456e553490e8
./bootstrap
make -f examples/Makefile-nrf52840 clean
make -f examples/Makefile-nrf52840 BORDER_AGENT=1 BORDER_ROUTER=1 COAP=1 COMMISSIONER=1 DISABLE_BUILTIN_MBEDTLS=1 DNS_CLIENT=1 DIAGNOSTIC=1 EXTERNAL_HEAP=1 JOINER=1 LINK_RAW=1 MAC_FILTER=1 MTD_NETDIAG=1 SERVICE=1 UDP_FORWARD=1 ECDSA=1 SNTP_CLIENT=1 COAPS=1 DHCP6_SERVER=1 DHCP6_CLIENT=1 NCP_SPI=1

rename and copy the five SPI files from /output/ and stash them in a safe location so they don't get cleaned up:

old name	new name
`libopenthread-ncp-ftd.a`	`libopenthread-ncp-ftd-spi.a`
`libopenthread-ncp-mtd.a`	`libopenthread-ncp-mtd-spi.a`
`libopenthread-rcp.a`	`libopenthread-rcp-spi.a`
`libopenthread-nrf52840-sdk.a`	`libopenthread-nrf52840-sdk-spi.a`
`libopenthread-nrf52840-softdevice-sdk.a`	`libopenthread-nrf52840-softdevice-sdk-spi.a`
`libopenthread-nrf52811-sdk.a`	`libopenthread-nrf52811-sdk-spi.a`

make -f examples/Makefile-nrf52840 clean
make -f examples/Makefile-nrf52840 BORDER_AGENT=1 BORDER_ROUTER=1 COAP=1 COMMISSIONER=1 DISABLE_BUILTIN_MBEDTLS=1 DNS_CLIENT=1 DIAGNOSTIC=1 EXTERNAL_HEAP=1 JOINER=1 LINK_RAW=1 MAC_FILTER=1 MTD_NETDIAG=1 SERVICE=1 UDP_FORWARD=1 ECDSA=1 SNTP_CLIENT=1 COAPS=1 DHCP6_SERVER=1 DHCP6_CLIENT=1 USB=1
rename and copy the two USB files from /output/ and stash them in a safe location so they don't get cleaned up:

old name new name

libopenthread-nrf52840-sdk.a libopenthread-nrf52840-sdk-usb.a

libopenthread-nrf52840-softdevice-sdk.a libopenthread-nrf52840-sdk-softdevice-usb.a
make -f examples/Makefile-nrf52840 clean
make -f examples/Makefile-nrf52840 BORDER_AGENT=1 BORDER_ROUTER=1 COAP=1 COMMISSIONER=1 DISABLE_BUILTIN_MBEDTLS=1 DNS_CLIENT=1 DIAGNOSTIC=1 EXTERNAL_HEAP=1 JOINER=1 LINK_RAW=1 MAC_FILTER=1 MTD_NETDIAG=1 SERVICE=1 UDP_FORWARD=1 ECDSA=1 SNTP_CLIENT=1 COAPS=1 DHCP6_SERVER=1 DHCP6_CLIENT=1
Copy the UART set of libraries from <OpenThreadFolder>/output/<target>/lib to the SDK folder: /external/openthread/lib/<target>gcc.
Copy the unique SPI and USB libraries from wherever you stashed them to the SDK folder: /external/openthread/lib/<target>gcc.
Copy the <OpenThreadFolder>/include folder to the /external/openthread folder.
Copy the platform specific platform-fem.h and platform-softdevice.h files from /external/project/openthread/examples/platforms/nrf528xx/src to the /external/openthread/include/platform folder.
Copy openthread-system.h file from /external/project/openthread/examples/platforms to the /external/openthread/include/platform folder.

Please confirm I haven't missed anything or if there is a more efficient way to achieve the same result.

Thanks,
Rob
